MUSIC-RACK.

To all whom it may concem:

Be it known that 1, JOHN SWEENEY, a citizen of the United States,residing at Johnstown, in the county of Cambria and State ofPennsylvania, have invented a new and useful Music-Rack, of which thefollowing is a specification.

This invention relates to music racks of that type designed to utilizeendless belts of printed music.

One of the objects of the invention is to provide simple mechanism foractuating the belts placed upon the rack, means being utilized wherebysaid belts can be operated at any desired speed.

' Another object is to provide a novel ar rangement of spools forholding the belts of music, said spools being designed to hold belts ofdifferent lengths and widths and to maintain them taut under allconditions while in use.

\Vith these and other objects in View the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :-Figure 1 is a front elevation of apparatus embodyingthe present improvements, a portion thereof being broken away. Fig. 2 isa plan view of the spools and a music-belt thereon, a portion of onewall of the motor casing being shown in section. Fig. 3 is a sideelevation of one of the spools and its supporting bracket, the guide forsaid bracket being shown in section. Fig. 4: is a view similar to Fig.3, but showing another spool and its bracket.

Referring to the ligurcs by characters of reference 1 designates a motorcasing in which is located a train of gears 2 designed to be actuated bymeans of a spring 3, which may be wound in the same manner as a clockspring. One of the gears of the train is secured upon a shaft 4:carrying a centrifugal governor 5, the sliding head (3 of which isdesigned to bear against a shoe 7 carried by one end of a controllinglever 8, which is fulcrumed at an intermediate point, as indicated at 9.A spring 10 connects one arm of the lever 8 with one wall of the casing1 and serves to hold the shoe 7 normally out of contact with the head 6.An adjusting Specification of Letters Patent.

Application filed July 22, 1909.

Patented Apr. 5, 1910.

Serial No. 508,993.

screw 11 is mounted within the casing 1 and is movable against lever 8so as to shift the shoe 7 in the direction of the head 6. A standard 12extends from the casing 1 and has an index 13 fulcrumed thereon asindicated at 141, one end of the index being connected to one end oflever 8 by a link 15. An arcuate scale 16 is carried by the standard andthe point of the index is designed to move thereover during theadjustment of the lever S by the screw 11.

The gears 2 actuate an intermediate shaft 17 one end of which projectsbeyond the casing 1 and has a beveled gear 18 secured to it. This gearmeshes with another beveled gear 19 secured to a trunnion 20 extendingdownwardly from an upstanding roller 21, which is supported upon abracket 22 secured to the casing 1, there being another bracket 23within which the lower end of the trunnion 20 is journaled. The lowerend of roller 21 is provided with a wheel 25 having a peripheral groove26, this wheel being formed with or secured to the roller 21 so as tomove therewith. A belt 27 is seated within the groove 26 and is alsoseated within a grooped wheel 28 formed at the lower end of a secondroller 29, which is ournaled at its lower end upon a bracket 30extending from the casing 1. It will be apparent therefore that when theroller 21 is driven by the gears 18 and 19, motion will be transmittedtherefrom through the belt 27 to the roller 2!), and both rollers willtherefore be caused to rotate simultaneously in the same direction.

An elongated supporting strip 31 is preferably extended from the housingor casing 1 and is provided, upon its front face, with opposed guidecleats 32, forming a groove or channel therebetaveen for the receptionof a head 33 formed on the back end of a substantially triangularbracket- 341, on the front end of which is journaled an upstandingroller 35. A bar 36 also has a head 33 in the channel and. this bar hasterminal cars 37 through which extends a pintlc 38. This pintle projectsinto the ends of the upper and lower arms of a bracket 39, there beingan upstanding roller 40 journaled upon this bracket 39. The roller 10and its bracket are preferably located adjacent one end of thesupporting strip 31, and a spring 11 may be attached to the bracket 39and bar 36 and constantly tends to swing the bracket 89 in the directionof the adjoining end of the strip 31.

The apparatus herein described is designed to be used in connection withbelts l4, of paper, cloth, or any other suitable material on which themusic is printed, the staif being extended in the direction of thelength of the belt, so that the music can be read continuously as thebelt is moved in the direction of its length by the rollers. Obviouslythe belts can be of different widths, this being dependent upon thenumber of staifs in a brace.

When it is desired to use the apparatus the diametrically opposedportions of the belt are placed upon the adjoining rollers 21 and 29while the middle portions of the two plies of the belt are placed uponthe rollers 35 and 40, it being apparent, by referring to Fig. 2, thatthe roller 35 is nearer the casing 1 than is the roller 40. As thespring ll constantly pulls upon the swinging bracket 39, it will be seenthat the roller &0 will hold the belt taut under all conditions. Afterthe belt has thus been placed in position the spring motor can be woundand set in motion, the screw 11 being first adjusted so as to controlthe operation of the governor 4, the speed of the belt being indicatedby the cooperating gage l6 and index 13. Motion will be transmitted fromthe motor through gears 18 and 19 to trunnions 20 and the roller 21 willtherefore be actuated and drive the belt 44. Motion will also betransmitted from the roller 21, through belt 27 to roller 29, the beltbeing thus positively driven at two points. As the belt travels towardthe left, the characters printed thereon can be read successively, and,after the belt has completed one circuit, the characters upon the nextlower staff or brace can be read. It will be apparent that, if desired,

more than one brace can be printed upon.

the belt, this being necessary particularly where very long compositionsare printed on the belt.

It is of course to be understood that various changes may be made in theconstruction and arrangement of the parts Without departing from thespirit or sacrificing the advantages of the invention. The brackets 84and 89 are obviously adjustable longitudinally along the supportingstrip 31, the

frictional contact between the head 33 and the cleats 82 beingsuflicient to hold them in any position to which they may be adjusted.

Should it be desired to drive the mechanism by means of an electricmotor one of the gears for transmitting motion to shaft 17 from spring 3may be loosened upon its shaft and the motor connected to the projectingend of the shaft 4,

What is claimed is 1. A device of the class described includ ingsimultaneously rotatable upstanding driving rollers, a motor foractuating the same, a guide, brackets slidably mounted within the guide,upstanding idler rollers adjustably supported by the brackets, anendless belt mounted on all of the rollers, and having a series of musicindicating characters extending in the direction of the length thereof,and means connected to one of the idler rollers for holding the belttaut.

2. A music rack for holding endless belts of music, including asupporting strip, guides thereon, heads adjustably mounted between theguides, a bracket fixedly connected to one of the heads, a bracketpivotally connected to the other head, means connected to said pivotedbracket for automatically shifting it in one direction, idler rollersupstanding from said brackets, driving rollers, and a motor foractuating the driving rollers, all of said rollers constituting supportsfor the music belt.

3. A device of the class described including a supporting strip, guidesthereon, heads adjustably mounted between the guides, a bracket fixedlyconnected to one of the heads, a bracket pivotally connected to theother head, means connected to said pivoted bracket for automaticallyshifting it in one direction, idler rollers upstanding from saidbrackets, driving rollers, a motor for actuating the driving rollers,all of said rollers constituting supports for an endless belt, means forcontrolling the operation of the motor, and an indicator for disclosingthe speed of a belt mounted on the rollers.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
